The function d(t) =300,000t represents the distance (in kilometers) that light travels in t seconds find d(15) and explain it's meaning

We were given the distance, d as a function of time, t.

.

To find , we put , in to

This implies that,

This means that in 15 seconds light covers a distance of 4,500,000 kilometers

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
